Back up your data
Back up the persistent volume mounted at /data. It contains your documents, database, settings and security keys.
Create a consistent backup
- Run
docker compose stopfrom your installation folder. - Snapshot or archive the complete data volume using your server’s backup tool. Find the volume name with
docker compose config --volumesand Docker’s volume inspection tools. - Run
docker compose startwhen the backup is complete.
Keep encrypted copies on separate storage. Treat backups as sensitive: they include documents and the keys needed to decrypt saved credentials.
Restore
Stop the installation, restore the complete volume and start it with the same image version used for the backup. Test restores on a separate installation before relying on them.
